Speeification of. Letters-latent No. 513, dated December .15, .1837.

To all 101L071 it may concern]:

Be it known that I, HORACE GLEASQN, of

Boston, in the county of Suffolk :and "Cominonwealth of Massachusetts,have invented a new and Improved Cooking-Furnace and Mode of Heating theSame; and I do hereby declare that the following is a full andexact-description.

My invention consists in constructing a compact .and portable apparatushaving all the conveniences for cooking .to fit into and be heated by acommoncylinder or upright stove -.to be removed therefrom .at ,pleasureand .placed out of the way when .not in use while the stove remains towarm the room, affording at a. trifling expense all .the conveniences ofthe largestcooking stoves which are now in use with the additionalconvenience of its being portable and capable of being removed from thestove by which it is heated and carried and used in any room where acylinder'stove is used, thus enabling small families and those who :wishto use economy in rent and fuel to cook in their parlors or sittingrooms, without the incumbrance of a common cooking stove.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

I have caused to be prepared drawings of said furnace indicating itsshape also sections of the same to which for the sake of brevity I willrefer.

Figure A represents the furnace with the boilers placed upon it andplaced over a cylinder stove. The body of the furnace is made of copper,tin, or sheet iron about two feet in length more or less according tothe size of the stove to be used the height and Width each about onehalf of the length. It has two doors opening into the oven one on eachside of the cylinder as shown by Nos. 1 and 2.

Figure E represents the cylinder stove over which the furnace is placed.

D represents the floor over the oven inside of the furnace which dividesthe box or body of the furnace into two posts about three or four inchesfrom the top forming a chamber over the oven into which the boilers set.No. 1 on said Fig. D is an aperture through which the cylinder passesinto the chamber the aperture is olong and about a foot in length topermit the heat to pass from the oven into the chamber when the oven isnot in use. No. 2 are sl des or damper-sanade toclose-oversaidappertureand-fit close to the. cylinder .to prevent the heat fromescaping from the oven. By these dampers the heat of the :oven and.thekboilers may be regulated :at pleasure. Nor-.3 is an opening forthefunnel offhe stove :back side of the furnace.

Iiii giire B represents .the back side of the furnace when placed overthe stove. No. 1

is the top of .the cylinder which gpasses .up .to

a level with the .top of .the furnace-f3 and 4 are the openings .toadmit the boilers. 2 is an opening in the back side of the furnace toadmit the funnel when placing ,the furnaceover the'stove. No. 5 is aslide to cover said openingand closeup around the funnel upon the,

which preventsthe heat from escaping from the oven. No. -6 is a hole fora small funnel to be described hereafter.

There is only one opening in the bottom ofthe furnace which is thatthrough which the cylinder passes and which is just large enough topermit the furnace ft-Q pass over the cylinder and rest upon theplatform of the stove, said opening being entirely closed by the top ofsaid plat-form. 0 is a diagram of said furnace showing both the out andinside and the stove upon which it is placed. There is no division inthe oven except that formed by the cylinder. The oven is supplied withgriddles as usual in stoves. The heat in the oven with a moderate firein the cylinder is intense so much so that water will boil therein in ashort time when all the doors and dampers are closed. Therefore tomoderate the heat of the oven and at the same time increase that underthe boilers I have placed at each end of the furnace a gage or standardmade of iron of. sufficient size to support the furnace for the purposeof raising or lowering the furnace upon the cylinder at pleasure, thisgage is represented by No. 3 on Fig. A, it rests upon the floor andpasses from thence through staples which are fastened to the furnace, isperforated with holes about half an inch apart and the furnace whenraised is held in its;

a moderate temperature. Where the oven is not in use and it is requiredto increase the heat under the side boilers, the furnace should beraised about an inch upon the cylinder and the dampers in the oven drawnaside in this case'the heat from the oven and that from the mouth of thecylinder is discharged into the chamber.

Figure F represents one of these furnaces same time the better toreflect the heat in the oven. The center hole in the top of the furnaceor that up through which the mouth of the cylinder comes is of the sizeof the outside of the cylinder the others of the size of the inside. Theboilers should be made to set into the chamber about two or three incheshaving a rim or projecting sides to prevent the heat from escapingaround them.

Hard coal, soft coal, or wood may be made use of in heating my furnace.One stick of wood of the size and length of a mans arm 'sawed intoblocks three inches long is sufficient to cook an ordinary meal foralarge family. The best'sized cylinder stove for this use is one abouttwelve inches in height and seven inches in diameter. By removing theordinary funnel from the cylinder stove and closing the openingrepresented by No. 2 on Fig. B the smoke and heat from the fiueofthestove is discharged into the chamber of the furnace and by removing theslide shown by No. 7 from the little funnel hole 6 the smoke passes offthat way. By this method the heat under the boilers may be increased.

lVhat I claim as my invention is Constructing a cooking furnace orapparatus having an oven, conveniences for boil ing and other culinarypurposes, the different parts thereof being united and of the shapeabove described without having attached to it any grate, chimney, orfireplace but having instead thereof a hole made perpendicularly throughit to admit a common cylinder or upright stove by which it is to beheated also applying to each end of said furnace a gage to produce theheat thereof at pleasure and making the whole compact and portable so asto be easily removed from the cylinder and placed out of the way whennot in use and it is for the invention of these improvements that I am'desirous of securing Letters Patent.

HORACE GLEASON.
